/* Hey look, some documentation [and in a place you expect to find it]!
|
|
|
|
The main reference for the pei format is "Microsoft Portable Executable
|
|
and Common Object File Format Specification 4.1". Get it if you need to
|
|
do some serious hacking on this code.
|
|
|
|
Another reference:
|
|
"Peering Inside the PE: A Tour of the Win32 Portable Executable
|
|
File Format", MSJ 1994, Volume 9.
|
|
|
|
The *sole* difference between the pe format and the pei format is that the
|
|
latter has an MSDOS 2.0 .exe header on the front that prints the message
|
|
"This app must be run under Windows." (or some such).
|
|
(FIXME: Whether that statement is *really* true or not is unknown.
|
|
Are there more subtle differences between pe and pei formats?
|
|
For now assume there aren't. If you find one, then for God sakes
|
|
document it here!)
|
|
|
|
The Microsoft docs use the word "image" instead of "executable" because
|
|
the former can also refer to a DLL (shared library). Confusion can arise
|
|
because the `i' in `pei' also refers to "image". The `pe' format can
|
|
also create images (i.e. executables), it's just that to run on a win32
|
|
system you need to use the pei format.
|
|
|
|
FIXME: Please add more docs here so the next poor fool that has to hack
|
|
on this code has a chance of getting something accomplished without
|
|
wasting too much time. */
